Abstract
A cyclone type, gas-liquid separator has a gas lead-through pipe penetrating an upper end wall of a cyclone chamber and extending downward to have a gas outlet in the cyclone chamber. A generally annular baffle plate is provided on an outer circumference of the gas lead-through pipe in the vicinity of the gas outlet to generally divide. the inside of the cyclone chamber into upper and lower. spaces. Accordingly, swirl flow formed in the upper space is prevented from being drawn directly by a negative pressure of the gas lead-through pipe without swirling sufficiently, so that separation efficiency is improved.
Claims14
A gas-liquid separator comprising:
- a generally cylindrical vessel defining therein a cyclone chamber and having a gas inlet being open on an inner circumferential wall of the cyclone chamber for introducing a gas into the cyclone chamber in a circumferential direction of the cyclone chamber for separating a liquid component from the gas by a centrifugal separation effect;
- a gas lead-through pipe having a gas outlet and communicating with the cyclone chamber through the gas outlet, the gas outlet being disposed separately from the gas inlet in an axial direction of the vessel;
- and
- a single baffle plate disposed in the cyclone chamber and, said single baffle plate generally dividing a space between:
- the gas outlet and the gas inlet to form a gas flow flowing from the gas inlet toward the gas outlet along the inner circumferential wall, wherein:
- said baffle plate is made of a rigid material that maintains its shape when the gas flow is applied to said baffle plate;
- and
- the gas lead-through pipe protrudes from the baffle plate at a side of said baffle plate that is opposite to the gas inlet,
- wherein the baffle plate and the cylindrical vessel define an unobstructed space around the gas lead-through pipe between the gas inlet and the baffle plate.
